- BACKGROUND
The expression of the inhibitor of apoptosis proteins (IAPs) family has not been fully investigated in colorectal carcinomas. This study investigated IAP expression in colorectal carcinomas and assessed their prognostic significance.
METHODS
Livin, XIAP, and SMAC/DIABLO expression was assessed by immunohistochemistry in 159 colorectal carcinomas. Correlations between protein expression and clinicopathological features were evaluated. The survival data analysis was estimated according to the Kaplan-Meier method.
RESULTS
Increased expression of IAPs in cancer tissues compared to surrounding nonneoplastic counterparts was observed in 67 cases (42.1%) for Livin, 50 cases (31.4%) for XIAP, and 68 cases (42.8%) for SMAC. A significant correlation was found between Livin expression and tumor differentiation, and SMAC expression and tumor location. The recurrence-free and overall survival of patients with low Livin expression were inferior to those of patients with high Livin expression (p=0.054 and 0.095, respectively).
High XIAP expression was significantly associated with shorter progression-free survival (p= 0.041).
CONCLUSIONS
Our study demonstrated that altered expression of IAP family members, including Livin, XIAP, and SMAC, is frequent in colorectal carcinoma. This result suggests that high Livin expression and low XIAP expression may be a favorable prognostic implication related to patient survival.

Abstract

- BACKGROUND
Survivin, a novel antiapoptotic gene has been linked with tumor development and progression in various human carcinomas including gastric carcinomas. The aim of this study was to evaluate the expression of survivin in gastric carcinoma and its correlation with tumor cell proliferation and apoptosis. METHODS: Expression of survivin was evaluated immunohistochemically in 84 surgically resected gastric carcinomas. Tumor cell apoptosis was evaluated with terminal deoxynucleotidyl transferase (TdT) mediated deoxyuridine triphosphate (dUTP) nick-end labeling (TUNEL), and Ki-67 immunostaining was used for evaluation of tumor cell proliferation. RESULTS: Expression of survivin was noted in 53.6% of the gastric carcinomas, and was significantly associated with depth of invasion, status of lymph node metastasis or tumor stage (p=0.022, 0.034, 0.040, respectively). There was an inverse correlation between survivin expression and apoptotic index (p=0.015). But there was no significant correlation between survivin expression and Ki-67 labeling index (p=0.430). CONCLUSIONS: These results suggest that survivin expression may contribute to tumor development and progression by inhibiting apoptosis in human gastric carcinoma.
